To all whom it may concern:

Be it known that I, THOMAS MURRAY,

a citizen of the United States, residing at New York, in thecounty of New York. and State of New York, have invented a certain new and'usefulIm rovement in Metal VehicleJVheels, of which the following is a specification.- Y

Ihe invention relates to metal vehicle wheels, and consists in the construction of the joint between the ends of the spokes and i the rim, whereby breakage thereat under shock or strain is prevented.

In theaccompanying drawings, Figure I is an elevation of my device. Fig. 2 is a cross section on the line (1:, w of Fig. 1. Fig. 3' is a modified form of my device in which the attaching flange is formed integral with spoke-instead of upon a separate sleeve, Fig. i is a cross section on the line y, y of Fig.3

I have also found this difliculty by providwith a flange. and securing the inner periphery of the rim or spots disposed in the ciring the spoke that flange to cun'iierential be free froin the rim. T hisintervening metal then by its own resiliencycounteracts thefapplied shocks or strains.

{In Fig. 1; A is bular metal spoke B is a portion of the rim (7 is a sleeve which receives the spoke and has a flange 1), preferably of elongated form, such as lenticular or elliptical, withits major axis in the circumferential line of the rim. Said flange is secured. preferably by welding, to the rim at two spots E. F,l)0tl1 in said c1rand the metal of the flange inter\'en spoke F is free from' the ing between the spots E.

I have found that breakage in metal wheels. and especially those used on automoline of said rim so. that the a metal intervenmg between said spots w1ll.

obstructions. The proper location of the two welds is easily determined once, for all for any chosen thickness of the flange metal.

Instead of forming the flange D on-'a sleeve 0 separate from the spoke, I may form'said flange integrally with the spoke itself, as shown in Figs. 2 and 3, and for the tubular spoke A, I may substitute a channelshaped spoke, as shown in Fig. 4, the flange I), D then extending from the flat sides of the spoke.

I claim: i g 1 2 1. A metal vehicle wheel, comprising a spoke, a rim, and a flange on the outer end of said spoke and secured to said rim at two spots disposed in the circumferential line of said rim, the said spoke and flange being free from Said rim-het\\'een said spots for a distance sufficient to cause shock or strain applied to the joint between rim and spoke to be counteracted by the re iliency of the metal intervening between s id spots.

:LAmetal vehicle wheel, comprising a hollow spoke, a rim. and a flange on the outer end of said spoke and homogeneously united to said rim at two spots disposed 180 degrees apart in the circumferential line of said run. the said spoke and flange being free't'rom said rim between said spots for a dista'mie sufficient to cause shock or strain applied to theijoint between rim and spoke to be counteracted by the resiliency of the meta] intervening between said spots.

3. A metal vehicle wheel. comprising a spoke. a rim. asleeye on the outer portion of said spoke. and a flange on said sleeve homogeneously united to said rim at two spots disposed in the circumferential lineot' said rim. the said flange and the butt end of said spoke between said spots being free from said rim for a distance sufficient to cause shock or strain. applied to thejoint between rim and spoke to be counteracted by the resiliency of the metal intervening between said spots. 4

. In testimony whereof I have aflixed my signature in presence of two witnesses.
